This is my simple, print-and-keep guide for setting up and using back-button focus on the Sony A7 IV. I keep these steps handy any time I’m shooting live musicians or low-light scenes around Ono Island.

Part A: One-Time Setup (takes about 3 minutes)

Step 1: Turn off autofocus on the shutter button

  1. Press MENU.
  2. Go to the AF/MF tab (purple).
  3. Select AF w/ Shutter.
  4. Set it to OFF.

Result: The shutter button will only take the photo, not re-focus.

Step 2: Make AF-ON your autofocus button

  1. Press MENU.
  2. Go to Setup (yellow tab).
